H w T m M 6 M% M Patented Jan. 24, 1 939 UNITED STATES PATENT OFFICE 1Claim.

This invention relates to a thread holder and/or cutter for spoolswhereby the loose end of the thread is securely held and prevented fromunwinding, and the holding means will also serve to sever the threadupon application of a pull on the thread.

An object of my invention is to provide a thread holder of the characterstated which is positioned on the end of a spool and which willeffectively hold or sever the thread in a novel manner.

Another object is to provide a thread holding attachment for spoolswhich is mounted on the end of the spool and which is provided withmeans to hold and sever the thread.

Still another object is to provide a thread holder which is simple inconstruction and inexpensive to manufacture.

Other objects, advantages and features of invention may appear from theaccompanying drawing, the subjoined detailed description, and theappended claim.

In the drawing Figure 1 is a top plan view of the thread holder mountedon a. spool. V

Figure 2 is a sectional view taken on line 22 of Fig. 1.

Figure 3 is a side elevation of the thread holder. 30 Referring moreparticularly to the drawing,

the numeral I indicates a disc formed of a light metal, which disc isapproximately the same diameter as the end of the spool 2. A pluralityof thread holding lugs 3 are struck up from the 35 disc I and are soarranged as to efiectively retain the thread in the space between thebottom of the lug and the upper face of the disc I. The disc I is madeof a very light sheet metal, and

consequently, the lugs 3 are quite thin so that the edges are somewhatknife-like and will sever the thread if said thread is pulled across oneedge of the 111%.

After the thread is cut on an edge of the lug 5 or lip, the loose end ofthe thread is pinched under the lip and thus retained so that the threadwill not unwind from the spool.

The spool 2 is provided with the usual center bore 4 and the disc I isremovably held on the 10 end of the spool by means of a pair ofdownwardly extending spring arms 5 which extend into the bore 4. Thearms 5 are also struck from the disc I and are bent downwardly so as tofit within the bore 4. The arms 5 may have sufficient spring therein tohold against the side of the spool bore, or a barb 6 may be formed oneach arm so as to bite into the wood of the spool. A circular hole I isleft in the center of the disc I conforming with the bore 4 so that thespool can be mounted on a sewing machine.

Having described my invention, I claim:

In combination with a thread spool having a bore therein, a threadholder comprising a metal disc, a pair of arms struck from the disc andbent downwardly, said arms extending into the bore whereby the disc isremovably mounted on the end of the. spool, said arms being cut from thedisc to form a central opening therein and said arms being greater inlength than the diameter of the central opening, and lugs struck fromthe disc and bent upwardly therefrom, said lugs being positionedadjacent the arms and on both sides thereof, said lugs being adapted tohold 85 and cut the thread.
